烏洛迦栴檀香（烏洛迦者西域蛇名其蛇常患毒熱投此香樹以身繞之熱毒便息故因名也或曰此蛇最毒螫人必死唯此旃檀能治故以為名耳）。

"Uraga sandalwood incense" (Uraga is the name of a snake in the Western Regions; that snake constantly suffers from toxic heat, so it throws itself upon this fragrant tree and coils its body around it, whereupon the heat-poison ceases, hence it is named accordingly; alternatively, it is said that this snake is extremely venomous, and if it bites someone they must die, but only this sandalwood can cure it, hence it is named after it).
